Behavior
If set to 0 (User ID/Password), the driver sends the user ID and password in clear text to the server for authentication.
If set to 4 (Kerberos Authentication), the driver uses Kerberos authentication. This method supports both Windows Active Directory Kerberos and MIT Kerberos environments.
If set to -1 (No Authentication), the driver passes the value anonymous for the user ID and the value p for the password when submitting requests to the server.
